--features as string

Are the --features flags passed to rustc/cargo somehow available as literal strings/array?
Rationale: I want to inspect what features a user given when doing some checks in 'build.rs'

Looks like you can use environment variables like CARGO_FEATURE_XYZ to detect this:

thanks least expected it as env var :slight_smile:
